Acoustic device
First Claim
1. A loudspeaker comprising a panel-form member capable of sustaining bending waves and having locations for at least one transducer to couple to plural low frequency modes, and at least one transducer mounted to the member at one of the locations to vibrate the member to cause the member to resonate to form an acoustic radiator which provides an acoustic output when resonating.

Abstract
Acoustic device including a member extending transversely of its thickness and capable of sustaining bending waves at least over an intendedly consequentially acoustically active area of the transverse extent of said member, the member having, by reason of orderly design methodology disclosed and claimed, a distribution of resonant modes of its natural bending wave vibration at least over said area that is dependent on values of particular parameters of said members, including geometrical configuration and directional bending stiffness(es), which values have been selected to predetermine said distribution of natural resonant modes being consonant with required achievable acoustic action of said member for operation of said device over a desired operative acoustic frequency range.
